How to add support for configuration files to your shell scripts.
miniforth is a real mode FORTH that fits in an MBR boot sector. The following standard words are available:
+ - ! @ c! c@ dup drop swap emit u. >r r> [ ] : ; load
Additionally, there is one non-standard word. s: ( buf -- buf+len ) will copy the rest of the current input buffer to buf, and terminate it with a null byte. The address of said null byte will be pushed onto the stack. This is designed for saving the code being ran to later put it in a disk block, when no block editor is available yet.
The dictionary is case-sensitive. If a word is not found, it is converted into a number with no error checking. For example, g results in the decimal 16, extending the 0123456789abcdef of hexadecimal. On boot, the number base is set to hexadecimal.
Backspace works, but doesn't erase the input with spaces, so until you write something else, the screen will look a bit weird.
See the blogpost, Fitting a FORTH in 512 bytes, for my motivation for writing this and the details of the code.
Hey! I'm @rstacruz and this is a modest collection of cheatsheets I've written.
I don’t want this to be Vega’s Opinionated Big Ass Book To Give You An All-In-One Education, both because VegaOpBABTGYAAIOEdu is far less catchy, and because I don’t even think it’s possible. The more I write on this the more I value input of others and other resources I find, and the more happy I am that I called this project Opinionated Guides.
A Guide. That’s what I want this to be. I want OpGuides to be a resource that’s like your friend you can come back to for advice on where to go next, and I think that’s something the internet really needs. Search engines are were awesome for finding information, but only when you know what to look for, so I figure OpGuides can be a sort of curated information source, with the crappy results filtered out, the best resources I know of included, and a healthy mix of entertainment in the education so that it’s not a chore to read.
Slingcode is a personal computing platform in a single html file. You can make, run, and share web apps with it. You don't need any complicated tools to use it, just a web browser. You don't need a server, hosting, or an SSL certificate to run the web apps. You can put Slingcode on a web site, run it from a USB stick, laptop, or phone, and it doesn't need an internet connection to work. You can "add to home screen" in your phone's browser to easily access your library of programs on the go. You can share apps peer-to-peer over WebTorrent. It's private. You only share what you choose.
Everything is kept in the browser's localstorage system.
It's written in Clojurescript with a bunch of dependencies, but the output is a single HTML page that you can drop anywhere. Probably easier to download it from the website (as recommended) and drop it someplace.
The classic book BASIC Computer Games, published by Creative Computing, inspired a generation of programmers. The games were written by many people, and compiled by David H. Ahl. The fabulous illustrations accompanying each game were done by George Beker.
I've included all the games here for your tinkering pleasure. I've tested and tweaked each one of them to make sure they'll run with Vintage BASIC, though you may see a few oddities. That's part of the fun of playing with BASIC: it never works quite the same on two machines. The games will play better if you keep CAPS LOCK on, as they were designed to be used with capital-letter input.
A curated list of awesome articles about falsehoods programmers make about things which are simply untrue.
In this book we will create a programming language together.
We'll start with 0 lines of code and end up with a fully working interpreter for the Monkey* programming language.
Step by step. From tokens to output. All code shown and included. Fully tested.
Through years of trial and error - skipping around internet radio stations, playing our entire music collections on shuffle, or just hammering single albums on repeat, we have found that the most effective music to aid prolonged periods of intense concentration tends to have a mixture of qualities. This is a site of mixes contributed by various people to hack to.
